'ATTACHMENI FOR PUMPS.

To on whom it may concern:

Be it known that '1, CHARLES VJ. LAKE, a citizen of the United States, residing at McPherson, in the county of McPherson and State of Kansas, have invented a new and useful Attachment for Pumps, of which th following is a specification. 7

The present invention relates to means applied to the so-called purifying well pumps, particularly the bucket type, the purpose of the invention beingto increase the purifying action of the pumps.

The so-oalled purifying wel'lpumps are so designated because of theagitating effect they have upon the water in the well and further'because of their construction. It is found however that wells which are not frepumps do not keep it pure and to expel [The present invention is an appliance either in the form of an attachment, to be applied to existing pumps or to be applied to pumps in their manufactureffor permitin the well back for the purpose of creat- :ing an; air circulation inithe upper portion of the well and for further agitating the water, thus resulting in greater aeration of the water and in the expelling of foul air and gases which accumulate above the surfaceof the water.

jWith the above and further objects in view the invention further resides in the sundry details of construction and in the v combination and arrangement inafter pointed out in detail.

In this 5 specification and the, annexed drawings, the invention is disclosed inthe form in which it 1s considered tobe the best,

but the invention is not limited to such form' because it is, capable of being embodied and it isfto be understood v the claims following the description here invention in' whatever form it may embody within the scope thereof;

'In the drawing is illustrated one form of pump to which the'invention is applicable 'andinwhich, c r Figure 1 illustrates the ordinary bucket :pu np i'n side'elevation'and the well in vertical section, the

Fig. 4 is, a top plan view of the pui'np shown in'Fig. 1. v I I Referring particularly to the drawings 1" indicates a well,'andj2 the usual form of endless bucket 'pump jmount'e d ,on the top of the well. The bucket pump comprises a casing 3 having mounted near its "upper portion a transverse shaft 4, having mounted thereon and within the casing theiis'ual sprocket wheel or pulley 5 over which passes an endless chain or cable 6 carryingthe'r'eon spaced buckets 7. The chain Or cable 6is'iof, such length as to extend to the well below the water level and,'in some instances, a lower sprocket wheel or pulley 8 maybe mountedbelow the water level in the well and over which pulley 8 the endless buckets pass.

The

shaft 4: is preferably providedlwith a gear 11 at its ends to mesh with a ge'a'rflQ on the usual crank handle 13,mounted exteriorly of the casing. It is also desirable in some instances to provide a pawl which may' be'moved into position to engage" the gear 11 for permitting rotation of thewheel 5 in but'one direction. I

A funnel or pocket 9 is providedwithim on the front wall there relation with respectto the'wheel or pulley '6, that the buckets 7 discharge thereinto as they pass over the wheel Ito'de scend into the well, as illustrated by the. f arrows in Fig.2. T he usual discharge spout 10 extends from the casing 3 of the'pump' and is in communicationwith the funnel 9.

Q The above is the usualconstruction of bucket pumps and forms no part of the present 111 'ventionexceptias may further appear by reason of the combination and arrangement of elements. The present invention consists offthe member 15" in'fthe formof a chute o'rtrou h provided with a bottom wall a, side walls Z), and end wall 0, the other end of the trough or chute being opened as illustrated. The chute 15 is secured in any suitable manner at the lower portion of the end wali c, to a shaft 16. The chute 15 is of such size and formation as to be suspended from the shaft 16, the ends of which are journalled in the side walls of the casing 3, and lie .over the entrance w of the funnel 9, the bottom wall a of the chute normally lying against the front wall of the casing 3 as illustrated particularly in Fig. 2. In this position of the chute 15 it is apparent that the water raised by the bucket 7 will be discharged into the funnel as usual, but, when the chute is moved to the position shown in Fig. 3, it will act as a valve for closing the entrance 9: of the funnel'and divert the raised water back into the well. The chute 15 is, preferably, at least of the same width as the funnel 9 so that its bottom wall a will entirely obstruct the entrance opening of the funnel, said walls of the chute acting to prevent water from flowing around the sides'of the chute into the funnel.

By reason of the inclined position of thechute the water is quickly diverted back 1 into the well in asteady stream which will cause a circulation of air in the pump and well above the water level in a manner understood. However, this downward stream of water will cause air circulation in the pump and aeration of the water in a manner well understood so as to relieve it of its impurities. This aeration of water is also assisted by the normal operation of the endless buckets agitating the water.

The chute 15 is operated by means of a crank handle 17 on one end of the shaft 16, the extremity of the handle being provided with a lateral finger or lug 18. To malntain the chute in the position shown in F ig. 3, for diverting the water back into the well,

a trip arm 19 is pivotally mounted to the casing in such relation with the handle 17 as to engage the handle and maintain it in" the desired position.

It will be observed from Fig. 1 of the drawings that the chute operating handle 17 normally lies in a depending position and is moved upwardly to place the chute in operative position. tioned the handle 17 assumes a substantially horizontal position.

The trip arm 19 is pivoted below the handle and is provided with a lateral offset portlon to engage under thechute handle 19 to I maintain it in its substantial horizontal'position by reason of the offset portion19 of the tr p engaging with the lug 18 of the chute tive position it is only necessary to slightly raise the handle 17 and move the trip arm to the position indicated in Fig. 1.

WVith the chuteso posipocket having a discharge outlet.

To release the chute from its opera 5 a casing, a discharge From the above it will be observed that a very simple and economical attachment has been provided for the ordinary purifying pumps which will cause the water to be diverted back into the well for the purpose of expelling the foul air and gases and for injecting fresh air into the well for areating the water. V v

In using the invention it is proposed that either after or before a supply of water has I been obtained that the operator place the chute in operative position, as shown in Fig. 3, and operate the pump for a desired period of time. leisure for the purpose of aerating the water and thereby always insure the freshness and purity of the water.

I claim: V

1. An attachment for well pumps equipped with a water-receiving chamber, means for delivering the water to the chamber and a Also the pump can be operated at ered to the chamber back into the well, said;

member normally lying in inoperative posi tion, and manually operable means for'maln taining the member 1n operative position,

whereby the water is diverted backinto the well for purifyingand aerating the water in the well. V I Y 3. In a pump, a water receiving chamber within the pump and having an open inlet, means for deliveringwater to the chamber,

and means arranged over the inletof said chamber and shiftable to a position to divert the water delivered to the chamber back into the well, a discharge spout for the pump, and

a connection between said spot and said chamber.

I 4. In a pump, a funnel-like water receiving pocket, means for raising water in the 7 pump and discharging it into the. pocket, a

trough-like member arranged over the fun- ,nel, saidtroughdike member beingpivotally mounted and normallya'ssuming an inopera tive position, and being movable to close said pocket and to divert the water being delivered to the pocket back into the well, said 5. In a well pump,

spout projecting from the caslng, a funnellike water-receiving pocket secured to a wall pf the casing and communicating with said spout, means for raising water in the pump and discharging it into the pocket, a troughlike member plvotally mounted over sald pocket and normally assuming an inoperative position, sai

d trough-like member being well, and manually operable means for releasably retaining the trough-like member in operative position.

In testimony whereof I have hereunto set my hand.
